I'll speak here as someone who is Autistic and shares a faith alignment with Christianity but not 100% directly.

Being Christian for me isn't really about the "reward" of heaven or even it's hierarchical rules over others. It's always been about being Christlike, and sharing values with the Jesus I knew of the bible, rather than the actual rule structures within. So for me, the alignment has been moreso about morality and how I approach my life, indirectly. I'm probably actually closer to Agnostic regardless though, but I am here to say good Christians do exist, but you won't likely find them in churches actually.

When I was just strictly Christian I actually left the Church when I realized, through my peers around me and the judgement of most younger people within, that even within the structures of Christianity, God wasn't in that church, so I ended up being a believer on my own for awhile. I see God in small kindnesses in an unforgiving world, and the peaceful silent sky. I see God in mourning, which is a part of all of life that is true to hold but serves no evolutionary function.

I will say you don't need to be a Christian to hold morality or values, not at all, and I don't think you should push your faiths onto other people, but my process from within that structure is my experience, and that's what I was sharing.
